Definitions

  • the invention relates to a luminaire with a lamp and with two or more mirrors which are partially transparent and - seen from the lamp - are arranged one behind the other, light passing through a mirror striking the mirror closest to the lamp in the light path.
  • the object of the invention is to provide a luminaire of the type mentioned at the beginning with a low glare effect, in which in particular punctiform light sources with high luminance, such as halogen lamps, can be used.
  • the light exit side of the lamp has one or more lenses made of transparent material, through which the light reflected by the partially transparent mirror emerges from the lamp.
  • the lamp luminous flux of a lamp is first broken down into individual luminous flux portions by the series-connected, partially transparent mirrors.
  • the individual luminous flux portions can have a wide variety of beam directions.
  • the entire light distribution curve of the luminaire is then obtained by adding the partial light distribution curves of the individual broken down luminous flux portions.
  • the invention current luminous flux portions.
  • the luminaire according to the invention is able through the outlet-side lens that distributes the luminous flux to create a broader radiating system from the light of a point-like light source, in which one achieves very high brilliance with very good shading through the spatial division.
  • FIG. 1 shows a first embodiment of a lamp according to the invention in a schematic longitudinal section
  • Fig. 2 shows a schematic cross section
  • Fig. 3 shows the shape of a partially transparent mirror before crooked
  • Fig. 4 shows a further embodiment in a schematic Longitudinal section
  • FIG. 5 shows a schematic cross section of this exemplary embodiment
  • FIGS. 6 and 7 each show further exemplary embodiments in schematic longitudinal sections.
  • the lamp shown in FIGS. 1 and 2 has a lamp 1, preferably a point-shaped halogen lamp with high luminance and brilliance.
  • This lamp 1 has a lamp reflector 2, which is advantageously connected to the lamp 1 to form a structural unit.
  • This lamp-lamp reflector combination emits a bundled luminous flux, preferably parallel rays, into the elongated and internally mirrored housing 3, which is open at the bottom in FIGS. 1 and 2.
  • a plurality of partially transparent mirrors 4 are arranged one behind the other in this housing 3.
  • the last mirror 4a can also be fully mirrored.
  • a light component (light beam l 1 ) reflected and another part (light beam l 2 ) passed. According to the invention, the light passing through then strikes another partially transparent mirror.
  • the light emitted by the lamp is thus divided into partial luminous fluxes, which already leads to a desired reduction in luminance.
  • three, preferably at least five, partially transparent mirrors 4 will advantageously be arranged one behind the other in order to achieve an appropriate reduction in luminance.
  • the mirrors 4 can be vapor-coated with a partially permeable or dichroic coating.
  • the partially transparent mirrors can be vapor-coated with uncoated transparent material, preferably tempered glass, the partial mirror effect being caused solely by the normal surface reflection.
  • the extent of this surface reflection can be varied by the angular position of the surface to the main direction of the light.
  • the proportion of reflection can be increased if the mirror surfaces are arranged at an angle to the incident light, preferably at an angle of at most 60 °.
  • the degrees of reflection and transmittance are concerned, it is advantageous if they vary substantially constantly, preferably by less than 10%, over the entire wavelength range of the visible light, so that disruptive color effects can be excluded.
  • the ratio of transmission to reflection will vary depending on the number of semi-transparent mirrors used, and in general the reflection will be lower and the transmission will be higher if more mirrors are connected in series. It has been shown that it is particularly favorable if the Percentage of the total amount of light incident on the mirror reflected by a partially transparent mirror is between 50 / n and 250 / n, preferably between 100 / n and 200 / n, where n is the number of partially transparent mirrors located one behind the other. If, for example, you have seven partially transmissive mirrors connected in series, as is the case with the exemplary embodiment according to FIG. 1, then the reflected portion per mirror should be roughly between 7 and 35, preferably between 14 and 28% of the amount of light incident on this mirror.
  • the partially transparent mirrors are formed from glass plates of constant thickness (for example 2 mm), which look like the view in FIG. 1 before the curvature according to FIG. 1.
  • This curvature results in a further reduction the luminance by expanding the incident parallel rays.
  • This beam expansion takes place in the drawing plane of FIG. 1.
  • the lamp is provided on the exit side with a lens 5 made of transparent material, through which the light reflected by the partially transparent mirrors 4 exits the lamp.
  • This lens 5 can be used to influence the light distribution curve again in the desired manner and further reduce the luminance and thus the glare.
  • the luminaire according to the invention can in particular be arranged next to a wall mirror, preferably to the edge of the mirror, and represents an alternative to the usual elongated fluorescent tubes, the light distribution and the color tone of the light being considerably better than these fluorescent tubes.
  • the partially transparent mirrors are advantageously arranged in a housing 3, which simultaneously functions as a holder for the partially transparent mirrors 4.
  • the partially transparent mirrors can in particular be arranged in a linear row at a distance from one another.
  • the lamp shown in FIGS. 1 and 2 deflects the light radiated in parallel from the end face of the housing 3 via the lamp or the reflector 2 essentially transversely to the longitudinal direction of the housing, where it passes through the lens 5 or a mere cover made of transparent material (without lens effect) emerges from a lateral light exit opening (bottom in FIG. 1) from the housing 3.
  • each light beam coming from the lamp 1 has been reflected at least once by a partially transparent mirror 4 before it emerges from the lamp. In other words, it is not possible to look directly at the lamp filament from the outside.
  • FIGS. 4 and 5 differs from the embodiment shown in FIGS. 1 and 2 essentially in that that the partially transparent mirrors are flat.
  • Such planar mirrors 4 therefore only slightly expand the parallel light beam radiated in from the front side of the housing 3 in the longitudinal direction of the housing, if at all.
  • This desired beam expansion is achieved in the embodiment according to FIGS. 4 and 5 by lens surfaces 5a on the one-piece lens body 5.
  • the beam is expanded in the transverse direction by the shape of the lens body 5 shown in FIG. 5.
  • the lamp 1 is essentially unshielded, i.e. it does not have a concentrating reflector 2.
  • Partially transparent mirrors 4 are provided on the left and right of the lamp, and a cover 6 can be arranged below the lamp.
  • a transparent block 7 for example made of glass or plastic
  • This block 7 has slot-like recesses 8, the boundary surfaces of which block 7 form the partially transparent mirror.
